“…It is possible that some of CP residues detected in this soil might be derived originally from HCB residue. Similar mechanism was also proposed in previous studies (Benoit et al, 1999;Ferdi et al, 2004;Do Nascimento et al, 2004).…”

“…CHCs and CPs are highly toxic, long persistent in soil and environment, and have a strong activity of enrichment in food chain (Irani, 1996;Reid et al, 2000;Torres et al, 1996). In soil and environment, CHCs can be converted into CPs through hydrolysis, oxidation, and microbial degradation processes (Benoit et al, 1999;Ferdi et al, 2004;Do Nascimento et al, 2004;Wegman and Hofstee, 1979). OPs are high toxic but short persistent, and PRTs are relatively low toxic and short persistent (Baker and Bottomley, 1982;Columé et al, 2001).…”

The residues of 31 chlorinated hydrocarbons (CHCs), 25 chlorophenols (CPs), 30 organophosphorus (OP) and pyrethroid (PRT) in two arable soils from the semi-arid and subtropical regions of China were assessed. Data obtained indicate that the main compounds of CHC pesticide residues in the semi-arid soil were 4,4'-DDE (25.3 ng/g) and beta-HCH (14.1 ng/g), which totally accounted to about 90% of total CHC residues detected. The total content of CHC residues detected in the subtropical soil was only 3.1 ng/g, of which approximately 50% was beta-HCH. However, the total content of CP residues in both of the soils was about 11 ng/g. In the semi-arid soil, only parathion-methyl amongst the 30 compounds of OP and PRT residues was detected (32.5 ng/g), whilst malathion and parathion-methyl (8.7 and 17.7 ng/g, respectively) detected in the subtropical soil. Based on these results, it was suggested the environmental risk of pesticide residues ranked in an order as CHCs (mainly as 4,4'-DDE, beta-HCH) > OP (parathion-methyl) > CPs for the semi-arid soil, and as OPs (parathion-methyl and malathion) > CPs > CHCs (beta-HCH) for the subtropical soil.

“…The classification of PCP − one of the most important contaminants, the concentration level of which should be monitored − was recommended by Borysiewicz (2008). The chemical was usually used for wood impregnation and removal of weeds (Nascimento 2004). The technical PCP can be contaminated (10-15%) with other chlorophenols such as triand tetrachlorophenol or polychlorinated dibenzo-pdioxins and polychlorinated dibenzofurans (Hughes et al 1985).…”

Combustion processes are considered to be the main source of the dioxin emission in the Baltic region. Pentachlorophenol (PCP) and its derivatives, pentachlorophenyl laurate (PCPL) and sodium pentachlorophenate (NaPCP) are known as precursors of dioxins. The research was conducted to obtain the first data on the concentration of PCDD/Fs and PCP in the bottom sediments of the Port of Gdansk. Toxicity (the Microtox® test) as well as several sediment parameters have been examined.In the surface layer of bottom sediments from the Port of Gdansk, all congeners of PCDD/Fs have been detected using GC-MS/MS. The positive correlation between toxicity and physicochemical properties of the analyzed bottom sediments confirms that these parameters are important in terms of environment contamination.

“…Prior to the analysis, carbonates were eliminated by treating the soil with 10% HCl and then air drying the vacuum filter recovered soil overnight. The soil organic matter (SOM) was obtained by multiplying measured organic carbon content of the soil by 1.724 (Nascimento et al, 2004). Soil pH was determined in distilled water at a soil-to-solution ratio of 1: 2.5.…”
