“…Considering that o,p'-DDT was not detected above MDL in any sediment samples from both Pina Sound and Suape Estuary, local use of dicofol can be ruled out as source of DDTs to the study areas. Miranda and Yogui (2016) draw similar conclusion in a study carried out on fish caught in coastal waters off Pernambuco.…”

“…Sediments from Suape Estuary seem to be contaminated by a lighter PCB mixture when compared to Pina Sound. Additionally, both estuarine PCB profiles also differ from the one observed in fish (Scomberomorus cavalla) caught off the coast of Pernambuco where tetra-through deca-CBs were detected in muscle and liver (Miranda and Yogui, 2016).…”

“…Nonetheless, they were found at high levels in sediments of Jaguaribe Estuary (Table 3) (Oliveira et al, 2016). In Pernambuco, α-chlordane and γ-chlordane have been found at detectable, quantifiable levels in tissues of offshore marine fish (Miranda and Yogui, 2016).…”

“…Legal use of OCPs in agriculture was phased out in the 1980s, and their use was prohibited in 1998 for public health purposes (Yogui et al, 2010). Despite their phase-out, PCBs and OCPs are still found in several environmental matrices along the Brazilian coast (e.g., Bícego et al, 2006;Fillmann et al, 2007;Miranda and Yogui, 2016;Oliveira et al, 2016).…”

“…Few studies have addressed POP pollution along the coast of Pernambuco, and none of them has investigated sediment contamination (Sericano et al, 1995;Miranda and Yogui, 2016;Anzolin et al, 2012). This is the first assessment of PCBs and OCPs in estuarine sediments of Pina Sound and Suape Estuary, northeastern Brazil.…”

The legacy of man-made organic compounds in surface sediments of Pina Sound and Suape Estuary, northeastern Brazil

Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are man-made organic chemicals that have adverse effects on aquatic organisms, sometimes altering ecosystem functioning with potential consequences for the coastal carbon cycle. This study assessed PCBs and OCPs in surface sediments of two estuaries with distinct historical land use on the coast of Pernambuco, northeastern Brazil. OCPs such as HCB, aldrin, dieldrin, isodrin, mirex, methoxychlor, endosulfans (α- and β-isomers), HCHs (α-, β-, γ- and δ-isomers) and chlordane-related compounds were below their respective limits of detection in all samples. Mean levels of PCBs in Pina Sound and Suape Estuary were 4.37 and 0.94 ng g-1 dry weight (dw), respectively. Average concentrations of DDTs in those same estuaries were 5.24 and 0.42 ng g-1 dw, respectively. No significant correlations were found between mud and contaminants (either PCBs or DDTs) at Pina Sound. In contrast, PCBs were significantly associated with mud at Suape Estuary. The greater contamination found at Pina Sound is consistent with land use of the urban, densely populated city of Recife. Residues of DDTs found in sediments of both estuaries reflect past local usage. Occasional adverse biological effects may be expected due to the levels of DDTs at several sites in Pina Sound. Lower levels of chemicals such as PCBs in the newly industrialized Suape Estuary suggest that a similarly low impact of legacy pollutants may be expected for future industrial enterprises around the world.

Detecting pesticide residues in human serum is a challenging process. In this study we developed and validated a method for the extraction and recovery of residues of multiple classes of pesticides from serum using one reagent. Salt‐assisted acetonitrile extraction and high‐performance liquid chromatography with quadrupole time of flight tandem mass spectrometry were used to quantitate 34 pesticides classified in nine groups of chemicals in human serum samples, which are frequently detected in food. The recoveries for 33 of analyzed pesticides ranged from 86 to 112% with relative standard deviations below 15%. The limits of quantitation and linearity of 31 of the pesticides were 1 µg/L and >0.990, respectively. The lower limit of quantitation has been reported in the literature particularly for multi‐classes pesticide mixtures in human serum. The salt–acetonitrile reagent was allowed to achieve good recoveries and detection limits, which could be attributed to salt altering the solvent polarity, preferentially collecting the organic phase in the solution, and promoting the extraction. The developed method was applied for two organophosphate pesticide metabolites, diethylphosphate and 3,5,6‐trichloro‐2‐pyridinol, in serum from rats that were fed a nonlethal quantity of chlorpyrifos. The concentrations of these two were 252.18 ± 15.47 and 0.63 ± 0.23 µg/L, respectively.

Pesticides are chemicals that have been specifically synthesised to “kill pests, including insects, rodents,fungiand unwanted plants” (WHO, WHO (World Health Organisation) (2020) The WHO recommended classification of pesticides by hazard and guidelines to classification, 2019 edition. Available at: https://www.who.int/publications/i/item/9789240005662 [Accessed 19 Aug 2020]). They are generally used with the aim of protecting plants or plant products and this is why they are referred to in European Union legislation as Plant Protection Products. Biocides are chemicals that are also designed to have the same properties as pesticides but they are not used to protect plants or plant products.
