The Efficacy of Experimental Angara Disease Vaccines
Formalinized aqua based liver organ vaccines for Angara disease (AD)/hydropericardium-hepatitis syndrome (HHS) are effective for the control of the disease. The experimental formalinized 10, 7.5 and 5% liver organ vaccines showed significant differences in efficacy from 2.5 and 1% liver organ vaccines. However, 10, 7.5 and 5% liver organ vaccines differed non significantly from one another. The...
متن کاملPersistent Organic Pollutants ("POPs")
Strictly speaking, all toxins entering the environment can be regarded as environmental poisons. Certain pollutants can, acting over long periods, harm living organisms even in low concentrations. This means that pollutants that are stable and thus persistent have a great ability to act as environmental poisons. Their stability means not only that their effects are long-lasting, but also that t...
متن کاملSerum Persistent Organic Pollutants
Persistent organic pollutants (POPs) are manmade organic chemicals that remain in the environment for years or decades. POPs are of special concern because they often remain toxic for decades or longer after release to the environment. The more persistent a toxic chemical is, the greater the probability for human exposure over time. Because they circulate globally long after being released into...
متن کاملPersistent organic pollutants and sedimentary organic matter properties: a case study in the Kishon River, Israel.
The Kishon River, the second largest coastal river in Israel, has been severely polluted for several decades. Sediments from upstream and downstream sites of the river were analyzed, lipid-extracted and evaluated for phenanthrene uptake. Total polycyclic aromatic hydrocarbon (PAH) concentration in downstream sediments was 299 microg kg(-1), consisting mostly of petrogenic-derived PAHs. Downstre...
متن کاملChapter 8 Persistent Organic Pollutants
The rapid growth in chemical and agrochemical industries during the last century have resulted in the environmental releases of a large number of new chemical compounds into the environment. According to the OECD, the daily use of chemicals includes about 70,000 mainly organic synthetic chemicals, and the number increases continuously (Schwarzenbach et al. 1993). Over the last decades, there ha...
