Interactions of micro and nano plastics




Interactions of emerging contaminants on micro(nano) plastics derived from both petrochemical and biodegradable plastics represents a serious threat to ecosystems and human health. Those emerging pollutants include metalloids (As & Sb), heavy metals (Zn, Cd, Hg, Cr, etc.), radioactive elements (radium & uranium), pharmaceuticals, personal care products and pesticides. To date, limited research can be found on generation of secondary micro(nano)plastics from disintegration of plastic objects under environmental conditions and their interactions with hazardous contaminants. Thus, it is crucial to understand mechanisms of physical and chemical interactions between secondary micro(nano) plastics and pollutants in different environmental and biological systems. Such interactions can adversely affect soil microbial structure, nutrient cycles, crop plant growth, food chains, aquatic creatures, and fish farming while directly influencing on global food production, drinking water quality and human health. Further, modern advancements of analytical techniques for concise identification and quantification of nano sized plastics are an urgent necessity. Hence, it is timely to investigate degradation mechanisms and fate of petrochemical and biodegradable plastics which are increasingly being utilized in current industrial, agricultural, and domestic practices. Understanding of recent advancements in micro(nano) plastic research in relation to interactions with emerging contaminants and transport mechanisms in environmental and biological systems along with analytical techniques and remediation strategies is of great scientific and practical significance. 

The scope of this special issue includes but is not limited to the following topics:

• Veracity of bioplastic degradation
• Interaction of secondary micro(nano)plastics with emerging pollutants
• Ecotoxicity and transport mechanisms of micro(nano)plastics
• Progression of analytical techniques
• Remediation strategies

Credit Card Payment Fraud & How to Avoid Theft

Image
Security and compliance often appear to go hand-in-hand these days. Problematically, many companies start with compliance then reverse-engineer security in a nearly futile attempt to protect data. In the payment card industry, the Payment Card Industry Security Standards Council (PCI SSC) established PCI Data Security Standard (PCI DSS) which sets the “gold standard” for compliance. Meanwhile, despite meeting the compliance standard, cardholder data (CD) remains a  primary target for cybercriminals . By understanding the seedy underbelly known as the Dark Web and the way Cybercrime-as-a-Service (CaaS) works, merchants and payment card processors can better secure CD from fraud and theft. What is payment card fraud and why is card information so valuable? Payment card fraud, also known as credit card fraud, is defined as the unauthorized use of a credit card, debit card, or similar payment tool. Cybercriminals often fraudulently utilize payment data to steal money or property from their

Internet Safety Rules

  Most of us rely heavily on the internet to enjoy social media, online education, remote work, and all sorts of entertainment. So, CYBERCLICK is sharing some information about " Internet Safety Rules " .   Rules To Be Followed: 1.  Keep your confidential data offline Identity theft cases made up the biggest single category of  crimes reported to the FTC in 2020 .     But cybercriminals cannot access or steal your personal information if it’s nowhere to be found on the internet.     That’s why some data — such as your Social Security Number — should just never go online. However, when you still have to share it, be sure to send it as an email attachment and   encrypt the file   before sending.   2. Check a website’s reliability As of January 17, 2021,  Google had registered more than 2 million phishing sites . But how do you tell a reliable site from a fishy one? First, look at the address line: It should have a little padlock at the beginning — this means the connection is

Spam and Phishing

Image
  Malicious Email A malicious email can look just like it comes from a financial institution, an e-commerce site, a government agency or any other service or business. It often urges you to act quickly, because your account has been compromised, your order cannot be fulfilled or there is another urgent matter to address. If you are unsure whether an email request is legitimate, try to verify it with these steps: Contact the company directly – using information provided on an account statement  on the company’s official website or on the back of a credit card. Search for the company online – but not with information provided in the email. Spam Spam is the electronic equivalent of junk mail. The term refers to unsolicited, bulk – and often unwanted – email. Here are ways to reduce spam: Enable filters on your email programs:  Most internet service providers (ISPs) and email providers offer spam filters; however, depending on the level you set, you may end up blocking emails you want. It’
