2016年11月8日 · Estimates of global PCB production (tons) as "pure" chemical (UNEP-POPS-COP.8-INF-10) It is important to note that due to dilution and cross-contamination, the mass of liquids and equipment containing or contaminated with PCB is much larger than the amounts of pure PCB produced: a single tonne of PCB can generate multiple tonnes of PCB wastes.

According to Annex A: Part 2 of the Stockholm Convention on POPs, each party shall eliminate the use of polychlorinated biphenyls (PCB) in equipment by 2025 and make determined efforts designed to lead to environmentally sound waste manage (ESM) of liquids containing PCB and equipment contaminated with PCB (having a PCB content above 0.005% (50 mg/kg)), as soon …

2023年11月14日 · Primary biliary cholangitis is a type of liver disease that damages the bile ducts. Early recognition and treatment may help prevent complications.

The PCB Elimination Network (PEN) is a multi-stakeholder mechanism that promotes and encourages the environmentally sound management of PCBs with a view to attaining the 2025 and 2028 goals of the Stockholm Convention. The PEN was established by the Conference of the Parties (COP) to the Stockholm Convention at its fourth meeting in 2009 (decision SC-4/5). …

2017年9月12日 · PCB, or polychlorinated biphenyls, are chemicals that have dangerous effects on the environment and human health. PCB have been used in many industrial applications such as transformers and capacitors. Although they are no longer allowed to be produced, they can still be found everywhere around us.

2023年9月8日 · To bridge the gap, the MedProgramme is supporting PCB-screening activities and laboratory analysis in partner countries. Thus, 451 tons of PCB-containing waste were verified in Algeria, and 271 tons in Lebanon. This evidence-based approach ensures effective disposal, in line with obligations under the Stockholm Convention.

2022年4月30日 · Premature ventricular contractions often cause few or no symptoms. But the extra beats can cause unusual sensations in the chest, such as:

2023年9月5日 · Polychlorinated biphenyls (PCBs) are persistent organic pollutants (POPs). Recognizing that women, men and children can be affected differently following exposure to PCBs and other POPs, this report emphasizes the importance of engaging women and men alike as part of the solutions that the Global Environment Facility (GEF) project “Disposal of PCB Oils …

The PCBs have been detected in atmospheric, marine, freshwater, groundwater, sediment, soil, food and biota samples, including human blood and milk. Electrical transformers, containing PCB oil, were still in use in 2002 in the Wider Caribbean Region and were reported in use in countries such as Panama and Guyana (UNEP 2002).

They cause immunotoxicity, skin problems, reproductive alterations and cancer in animals, particularly in marine species such as the common seal, whale and salmon. PCB-containing equipment such as old transformers, TVs, fluorescent lights, and fridges, are still in use and must be replaced with PCB-free alternatives.
