The most commonly observed health effects in people exposed to extremely high levels of PCBs are skin conditions, such as chloracne and rashes, but these were known to be symptoms of acute systemic poisoning dating back to 1922. Studies in workers exposed to PCBs have shown changes in blood and urine that may indicate liver damage.
Pentachlorophenol (PCP) is an organochlorine compound used as a pesticide and a disinfectant.First produced in the 1930s, it is marketed under many trade names. [5] It can be found as pure PCP, or as the sodium salt of PCP, the latter of which dissolves easily in water.
The inclusion of PCBs as a PBT may be attributed to their low water solubility, high stability, and semi-volatility facilitating their long range transport and accumulation in organisms. [5] The persistence of these compounds is due to the high resistance to oxidation, reduction, addition, elimination and electrophilic substitution. [ 6 ]
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
Analysis of eggs and ducks found dioxin levels 15 times higher than the EU limit and a high concentration of dioxin-like PCBs in the village of Libiš. [73] In 2004, the state health authority published a study which analysed the level of toxic substances in human blood near Spolana.
People who are in the category of being overweight are also more likely to have high blood pressure. Reducing weight through lifestyle changes and/or through medications will also result in better ...
There have been numerous incidents where people have been exposed to high doses of TCDD. In 1953, an accident occurred at BASF during the chlorination of diphenyl oxides, as a result of which several workers developed severe chloracne. Similar cases had occurred 6 years earlier in the USA and in 1952, 1954 and 1956 at the Boehringer Ingelheim ...
A study based on a representative sample of the population of Catalonia (Spain), [32] which integrated the number of compounds detected per person and the concentration of each compound, found that more than half of the population had concentrations in the top quartile of 1 or more of the 19 persistent toxic substances (PTS) (pesticides, PCBs ...
