Bisphenol A was largely reported from urban ecosystems in Asia, Europe, and North America; unfortunately, information was lacking from large geographic areas, megacities, and developing countries. When sufficient data were available, probabilistic hazard assessments were performed to understand global environmental quality concerns. Exceedances of Canadian Predicted No Effect Concentrations for aquatic life were > 5. Asia, Europe, and North America but as high as 8. Asia. Similarly, maximum concentrations of BPA in sediments from Asia were higher than Europe. Concentrations of BPA in wildlife, mostly for fish, ranged from 0. We observed 6. 0% and 4. US Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey in Europe and Asia, respectively. These findings highlight the utility of coordinating global sensing of environmental contaminants efforts through integration of environmental monitoring and specimen banking to identify regions for implementation of more robust environmental assessment and management programs. Keywords: urban ecosystems, biomonitoring, environmental exposure, probabilistic hazard assessment. Introduction. As countries develop and urbanize, production demands, such as food and beverage packaging, medical equipment, electronics, flame retardants, adhesives, building materials, automobiles, and paper coatings increase globally (Staples et al. Saal and Hughes 2. Kanga et al. 2. 00. Calafat et al. 2. Chapin et al. 2. 00. Flint et al. 2. 01. As a result, consumption of bisphenol A (BPA), 2,2- bis(4- hydroxyphenyl) propane (CAS No. Commercial production of BPA began in the United States in 1. Europe a year later. Growth of global production has consistently ranged between 0% and 5% annually, with the latest strongest growth occurring in China (Burridge 2. In fact, between 2. BPA market in Asia alone grew at an average of 1. Huang et al. 2. 01. In 2. 00. 4, the estimated production of BPA in the United States was approximately 1 million tons (2. Western Europe in 2. European Commission Joint Research Center 2. U. S. National Toxicology Program 2. Therefore, BPA is classified as a high production volume chemical in the United States. The purpose of this review was to examine the occurrence of BPA in the natural environment throughout different regions of the world. We included over 5. BPA measured in aquatic systems, wildlife, and humans. This compilation of data on BPA was intended to support an understanding of region- specific environmental occurrence, exposure, and bioaccumulation. Sources of BPABisphenol A does not occur naturally but has become ubiquitous in the environment as a result of its high production, consumption, and subsequent environmental introduction (Tsai 2. Environmental sources of BPA can be classified as preconsumer and postconsumer products. Preconsumer sources include those attributed to the manufacture of BPA and BPA- containing products, where the first source of BPA release is from effluent discharge of manufacturing plants (Staples et al. Cousins et al. 2. Klecka et al. 2. 00. Transport and processing of BPA and BPA- containing products are additional sources for its preconsumer release (Staples et al. Flint et al. 2. 01. Postconsumer sources include those associated with disposal or waste including effluent discharge from municipal wastewater treatment plants (WWTP), leaching from landfills, combustion of domestic waste, and degradation of plastics in the environment (Teuten et al. Fu and Kawamura 2. Flint et al. 2. 01. In 2. 00. 0, Fürhacker et al. BPA was removed during wastewater treatment in a plant located in southern Austria; similar findings were reported in the United States (Dorn et al. However, despite efforts to treat BPA, detection in the environment continues to be reported (Fromme et al. Leusch et al. 2. 00. Mussolf et al. 2. Xu et al. 2. 01. 4a, b). For example, detection of BPA was reported up to 1. L in hazardous waste landfill leachates from Japan (Yamamoto et al. L in effluents in the United States (Kolpin et al. In addition to environmental occurrence, contact with heat and acidic or basic conditions accelerates the hydrolysis of the ester bonds between BPA molecules, which results in human and domesticated animal exposure from heating of cans to sterilize food, the presence of acidic or basic food or beverages in cans and polycarbonate plastic, and repeated heating and washing of these products (Howdeshell et al. Kang et al. 2. 00. Vanderberg et al. Goetz et al. 2. 01. Inhalation of indoor dust and dental sealants represents other sources of human exposure (Olea et al. Calafat et al. 2. Geens et al. 2. 00. Bisphenol A is synthesized by the condensation of phenol with acetone in the presence of a catalyst, a strongly acidic ion- exchange resin. The molecular structure of BPA consists of a central tetrahedral carbon atom with 2 methyl groups and 2 phenol groups (Table 1). Bisphenol A is a moderately water- soluble compound (1. L at room temperature; US Environmental Protection Agency, 2. Ka 1. 0. 2. 9 ± 0. The U. S. National Institutes of Health Hazardous Substances Data Bank reports a log Kow of 3. BPA. Thus, BPA would be historically considered to possess moderate bioaccumulation (Staples et al. Heinonen et al. 2. Valenti et al. 2. Nichols et al. 2. In addition, low volatility results from low vapor pressure, high melting point, and moderate solubility (Staples et al. Rapid photo- oxidation and breakdown in the atmosphere explains the low half- life of BPA in air (0. Despite the low half- life and only a moderate potential for bioaccumulation, BPA has been detected in multiple environmental matrices (eg, water, soil, and air), including wildlife and humans as subsequently discussed further below. Physicochemical Profile of Bisphenol A. Bisphenol A in Effluent and Surface Water. Detection of BPA in water began in the late 1. Figure 1). Publication topics span from chemical and biological detection and quantification method development studies to best management practice studies on the transformation of BPA prior to environmental release (e. Although BPA is a highly studied compound, we examined the literature to gain an understanding of its relative distribution in various parts of the world (Figure 2). For example, water occurrence studies largely have occurred in Europe, Asia, and North America with 8. Figure 2; Supplemental Table S1). Notably, no published studies were identified from Russia, India, South America (with Brazil as an exception), Central America, or Africa (with Tunisia as an exception). Thus, although we report and analyzed global patterns of freshwater BPA contamination, it is largely comprised of data from 3 continents and lacks data from the majority of developing countries around the globe (Figure 2). Historic overview of the number of publications per year among geographic locations reporting detection of bisphenol A (BPA) in (A) surface water and effluent; (B) sediment, soil, biosolids, and air; and (C) wildlife collected in the field including mammals.. Number of publications by continent or global region reporting detection of bisphenol A (BPA) in (A) surface water and effluent; (B) sediment, soil, biosolids, and air; and (C) wildlife collected in the field including mammals, birds, fish, reptiles.. Bisphenol A concentrations in WWTP effluent ranged from nondetect to 3. L, but in most cases, effluent levels were less than 5 μg/L (Supplemental Table S1). Limit of detection among studies also displayed a wide range from 0. L to 1. 0 μg/L, which inherently resulted from inconsistencies among the specific analytical methods employed in each study. Technological advances often result in analytical improvements for instrumental precision, accuracy, and sensitivity through time.

The Pangu Team (Chinese: 盘古越狱团队; pinyin: Pángǔ yuèyù tuánduì), is a Chinese programming team in the i. OS community that developed the Pangu jailbreaking tools. These are tools that assist users in bypassing device restrictions and enabling root access to the i. OSoperating system.
This permits the user to install applications and customizations typically unavailable through the official i. OS App Store.[1]Etymology[edit]In some versions of Chinese mythology, the name usaama (or Pan Gu) is the Chinese (Chinese: 盘古) word for the first living being and creator of all.[2]Pangu jailbreak[edit]Pangu or Pangu Jailbreak for i. OS 7. 1 - 7. 1. x is a free i. Update : Content of this article has outdated! Please follow Current status of iOS 9.3.4 / 9.3.5 jailbreak for Cydia download your iPhone, iPad & iPod. Apple has. OS jailbreaking tool developed by the Pangu Team that is capable of executing jailbreaks on various i. OS 7. 1 devices (i. Pod touch, i. Phone and i. Pad) by using various exploits. The tool was first released on 2. June 2. 01. 4 UTC+0. OS 7. 1 on all i. OS devices and the new fourth generation Apple TV (for tv. OS 9. 0 and 9. 0. The initial release of the tool included support for i. OS 7. 1. 2. This was because the team suspected that a firmware update was imminent, and Apple would use that release to patch the vulnerabilities used in the tool. Controversy[edit]Pangu uses a revoked enterprise certificate to inject the jailbreak, which is removed after the jailbreak is complete.[4]In the initial release (v. PP, a Chinese cracked app store would be installed if the user did not uncheck the check box that was checked by default during installation.[4] 2. · How to restore your device to iOS 9.x with iDeviceReRestore; Fixing size mismatch errors in Cydia when trying to install a tweak; How to find offsets for. PP was removed from the package as of version 1. Originally (in v. Pangu achieved the jailbreaking using an Infoleak vulnerability taken from Stefan Esser's (AKA: i. Although the team acknowledges Esser's help within the Pangu jailbreak tool, Esser took to Twitter to let everyone know he was "in no way okay" with Pangu using the exploit he discovered.[6]One of the Pangu members, Daniel_K4, later responded to the public that no one was asked to sign the NDA during the paid security training sessions, and the Infoleak bug was known to everyone that attended the security training sessions. Daniel_K4 said that they too have found a similar vulnerability in Infoleak, but it was not used since they didn't want to disclose any new vulnerabilities. The Infoleak bug was used to bypass the KASLR which will not make an untethered jailbreak alone. The team said they never thought using what they had learned from a paid class would be wrong.[5]Pangu offered Esser another vulnerability of their own as compensation but received no response.[5] Thus, since version 1. Esser's Infoleak was replaced with another vulnerability found by Pangu.[7]Pangu 8[edit]. Pangu app running on i. OS 8. Pangu. 8 or Pangu Jailbreak for i. OS 8. 0 - 8. 1 is a free i. OS 8 jailbreak tool from the Pangu Team. It was first released on October 2. UTC+0. 8: 0. 0. The tool is compatible with all devices capable of running i. OS 8 (i. Phone 6, i. Phone 6 Plus, i. Pad mini 3, and i. Pad Air 2), and is currently available in both Chinese and English. Cydia was not included in the initial release package, but was added in v. Pangu website.[8]Pangu app[edit]Since Cydia was incompatible in the initial release, Pangu. Pangu app that allows users to install Cydia, alongside various Pangu bug fixes and recommended software. The tool works as a tweaking utility and also recommends tools such as Open. SSH. After Cydia is installed, the Pangu app can be removed from the device by removing the "Pangu loader for i. OS" from Cydia and respringing the device.[9] Uninstalling the Pangu app is not the same as removing the Pangu jailbreak. If i. OS users remove Pangu jailbreak then they have to restore their device to the latest i. OS version. Moreover, it's difficult to downgrade an i. OS device back to the previous i. OS version because Apple stops signing the old i. OS versions after the release of a newer i. OS firmware.[1. 0] The initial releases also enabled for Cydia to be installed through a Debian package file instead of within the Pangu app as an alternative. Pangu 9[edit]Pangu. Pangu Jailbreak for i. OS 9. 0 - 9. 1 is the latest free i. OS 9 jailbreak tool from the Pangu Team. It was first released on October 1. UTC+0. 8: 0. 0.[1. OS 9. 0 - 9. 0. 2. On March 1. 1, 2. Pangu released Pangu. OS 9. 1. The tool is capable of jailbreaking all devices running i. OS 9. 0 and all 6. OS 9. 1. It is currently available in English. There are both Windows and OS X versions available. Cydia was bundled with Pangu. Pangu app found in previous Pangu jailbreaks. PP2. 5 Assistant (PP助手) 5. Released on July 2. PP2. 5 also known as Pangu. Pangu. 9 is a jailbreak for i. OS 9. 2 - 9. 3. 3 that is only supported for 6. Pod 6th gen and i. Pad Pro (on the 1st release). The application known as PP Assistant which is a Chinese program that can install cracked apps. The Pangu jailbreak is bundled with PP Assistant that has the option to install the PP2. During the jailbreak process it will ask for an Apple ID used to install the unofficial app to jailbreak. The English version was released, adding support for the i. Pod 6th Gen and the i. Pad Pro but will most likely not add support for 3. OS 9. 3. 1. 35. 02. Apple corrected the "IOMobile. Frame. Buffer" bug in i. OS 9. 3. 4, released on August 4, 2. Team Pangu” was creditied as the source for this update in the official security notes.[1. Apple states: "Available for: i. Phone 4s and later, i. Pad 2 and later, i.

OS High Sierra for its desktop computers is also getting ready to debut September 2. While its predecessor, Sierra, was packed with new features like Siri integration, Night Shift software for easing eye strain during late- night use, and Apple’s solid- state- optimized Apple File System, High Sierra’s changes are mostly under the hood. It supports the same devices supported by Sierra, so if you’ve got the old version you’re good to go when upgrading to its successor. According to Apple, “All Macs introduced in mid 2. Mac.

Just click the Apple logo in the top- left corner of your display, select “About This Mac,” and take a look at the name of your device, which should include its manufacturing year. You can also use Apple’s serial number identification page that provides you with even more information about your Mac, such as its purchase date, Apple. Care Protection Plan status, and repair coverage. If you find your Mac or i. OS device unable to receive the new software, don’t fret too much. Newer software takes advantage of newer hardware, meaning your older device might simply find the update too intensive for its outdated hardware. It’s a bummer, but at least you can turn your vintage tech into cash by trading it in. Instagram Done Got Hacked. Instagram, Facebook’s hotter, snootier subsidiary, may have a massive data breach on its hands. This week, a security flaw within Instagram allowed hackers to assemble a database of what appeared to be verified users’ contact information—some of those affected purportedly being celebrities and politicians. According to the Verge, Instagram now says the known scope of the breach has expanded to include at least some unverified Instagrammers.“.. We recently discovered a bug on Instagram that could be used to access some people’s email address and phone number even if they were not public,” Instagram CTO Mike Krieger wrote in a blog post. No passwords or other Instagram activity was revealed. We quickly fixed the bug, and have been working with law enforcement on the matter. Although we cannot determine which specific accounts may have been impacted, we believe it was a low percentage of Instagram accounts.”“We are very sorry this happened,” Krieger added. As the Daily Beast reported last week, the unknown hackers behind the breach claim to have compromised six million accounts and set up a website called “Doxagram,” which allegedly offered access to phone numbers, email addresses or both for 1,0. Instagram accounts at $1. While a few of the addresses were public information, “many did not return any relevant Google results, implying they were obtained from some private source.” The Beast was able to confirm some of the leaked accounts had valid contact information; the site was later taken offline. Per the Verge, cybersecurity firm Rep. Knight said supposed contact information for a number of celebrities featured on Doxagram was circulating on the dark web, ranging from Hollywood celebs like Emma Watson and Leonardo Di. Caprio to musician Harry Styles and boxer Floyd Mayweather. The Beast claimed the site even purported to have contact info behind President Donald Trump’s official Instagram profile, which was managed by White House social media director Dan Scavino. In addition to potentially exposing users to harassment, the breach could allow hackers to target them for social engineering attacks which could compromise their accounts. Instagram’s security hole may be linked to an incident on August 2. Selena Gomez—the most- followed user on the site—and posted nude photographs of Justin Bieber. Data breaches are not the only major problem reported at the social- media giant in recent days. On Friday, Mashable reported the site’s staff is rife with individuals willing to verify Instagram accounts for prices “anywhere from a bottle of wine to $1.

General Retention policy for replication jobs is now processed concurrently for multiple VMs in the job, as opposed to one by one, reducing the overall job run time. Added email notification about File to Tape and Backup to Tape jobs waiting for user interaction (for example, when a tape medium needs to be inserted by the user)VMware Tools quiescence should now log an informational event when VMware Tools are outdated, as opposed to a warning event. Independent virtual disks which are explicitly excluded from processing in the job settings should no longer log a warning during the first time when the given VM is being backed up. Virtual Lab proxy appliance was upgraded to virtual hardware version 7 to allow for it to manage more networks out of box. Jobs should no longer appear to "hang doing nothing" in some circumstances, with the duration not ticking for any event in the job log.

To enable identity verification of the remote server, SSH key fingerprint is now displayed to a user when registering the new Linux server. Accepted SSH keys are stored in the configuration database to protect from MITM attack. Performance enhancements. Added experimental support for direct data movers communication when both are running on the same server (for example, when backing up to a local storage on backup proxy server). If your local backup jobs report Network as the bottleneck, and you see high load on some backup proxy server NICs when the data was supposed to stay local to the server, you are likely to benefit from this behavior modifier. To enable alternative data exchange path, create the Data. Mover. Local. Fast.

Full VM restore process puts all virtual disks to the datastore selected for VM configuration file,ignoring virtual disks placement settings specified in the wizard. In certain environments, jobs fail to process VMs in Direct SAN Access mode with the "Failed to create processing task for VM Error: Disk not found" error. Dismounting processed virtual disks from backup proxy server takes longer than expected in the Virtual Appliance (hot add) processing mode. Rescan of v. Center server containing hosts without HBA and SCSI adaptors fails with the "Object Reference not set to an instance of an object" error. Replication jobs to a cluster fail with the "The operation is not allowed in the current state" error if chosen cluster host is in the maintenance mode. Under rare circumstances, jobs with Backup I/O Control enabled may occasionally log the "Operation is Retrieve. Properties. Operation" related errors. Enabling Backup I/O Control limits snapshot removal tasks to one per datastore regardless of datastore latency levels. VM Copy jobs always fail over to the Network (NBD) processing mode. VMs with virtual disks having the same names but with different capitalization, and located on the same datastore cannot be backed up. Backing up v. Cloud Director v.

Existing Hyper- V backup and replication jobs processing VM with SCSI disks start to consume x. Removing a node from a cluster does not remove the corresponding node from the cluster on the Backup Infrastructure tab of the management tree until the next periodic infrastructure rescan (in up to 4 hours). Replication from backup fails with the "Virtual Hard Disk file not found[/id" error if backup job that created this backup had one or more disks excluded from processing. Under rare circumstances, legacy replicas using non- default block size may fail with the "[i]FIB block points to block located outside the patched FIB" or "Block offset [] does not match block ID []" error messages. Offhost backup from Windows Server 2. R2 fails with the "Exception of type 'Veeam. Backup. Agent. Provider. Agent. Closed. Exception' was thrown" error when processing a VM that can only be backed up in Saved or Crash- Consistent states, and native Hyper- V quiescence is enabled in the job settings. If a Hyper- V cluster node goes offline during backup from shared volume snapshot, and does not recover until the Veeam job fails, CSV volume backup infrastructure resource will not be released by the scheduler.
