“…The accumulation of hydrophobic organic chemicals by invertebrates has proven useful in environmental monitoring for polychlorinated biphenyls (PCBs) [1], organochlorine pesticides (OCPs) [2][3][4], polychlorinated benzo-p-dioxins and furans (PCDD/F) [1,5] and organophosphate insecticides (OPs) [3,6,7]. Many of these chemicals are known to cause sublethal effects in aquatic organisms, including reproductive impairment and decreases in hatching success [8][9][10].…”

Invertebrates have long been used as resident sentinels for assessing ecosystem health and productivity. The shore crabs, Hemigrapsus oregonensis and Pachygrapsus crassipes, are abundant in estuaries and beaches throughout northern California, USA and have been used as indicators of habitat conditions in several salt marshes. The overall objectives of the present study were to conduct a lab-based study to test the accumulation of current-use pesticides, validate the analytical method and to analyze field-collected crabs for a suite of 74 current-use and legacy pesticides. A simple laboratory uptake study was designed to determine if embryos could bioconcentrate the herbicide molinate over a 7-d period. At the end of the experiment, embryos were removed from the crabs and analyzed by gas chromatography/mass spectrometry. Although relatively hydrophilic (log K(OW) of 2.9), molinate did accumulate with an estimated bioconcentration factor (log BCF) of approximately 2.5. Following method validation, embryos were collected from two different Northern California salt marshes and analyzed. In field-collected embryos 18 current-use and eight organochlorine pesticides were detected including synthetic pyrethroids and organophosphate insecticides, as well as DDT and its degradates. Lipid-normalized concentrations of the pesticides detected in the field-collected crab embryos ranged from 0.1 to 4 ppm. Pesticide concentrations and profiles in crab embryos were site specific and could be correlated to differences in land-use practices. These preliminary results indicate that embryos are an effective sink for organic contaminants in the environment and have the potential to be good indicators of ecosystem health, especially when contaminant body burden analyses are paired with reproductive impairment assays.

Seafood is one of the major sources of protein and functional components that are crucial to human health and is an important part of the diet in many countries. On the other hand, seafood usually contains residues of persistent environmental pollutants (PEPs), such as organohalogen compounds: polychlorodibenzodioxins (PCDDs) and polychlorodibenzofurans (PCDFs) namely dioxins, polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs), and heavy metals (mercury-Hg, arsenic-As, cadmium-Cd, and lead-Pb). Dietary intake is the major contributor of human exposure to these contaminants and seafood has the greatest risk due to its high lipid content. These lipophilic chemicals accumulate in fatty tissues of marine organisms and are subsequently transferred to humans through the food chain, damaging ecosystems and human health.PEPs in seafood have gained special attention from consumers, scientists, and environmental and governmental organizations due to their widespread consumption. Several studies have determined PEPs in aquatic organisms from freshwater and marine environments. Beside the marine ecosystem, products from aquaculture are also associated with increased risk of contamination by these pollutants, as well as antibiotic residues. This chapter discusses the wide range of studies on seafood contaminants and the factors behind the contamination. Furthermore, regulations for these contaminants and recommendations to reduce the risk of contamination are provided. Persistent environmental pollutants (PEPs) Organohalogen compounds (OCs)OCs is a group of chemically stable, carbon-based, and ubiquitous compounds characterized by low volatility and high lipid solubility.

“…The total concentration of PBDEs in mussels was 13.8 ng/g lipid in Qingdao coastal sea [11]. A few PBDE congeners (BDE-47, 99, 100, and 28) were found in crustacean muscles (spider crab, edible crab, velvet swimming crab, and Norway lobster) from coastal waters Brittany and Normandy (France) [12]. The total concentration of PBDEs ranged from 0.38 to 9.19 ng/g wet weight in mussels (Mytilus coruscus and M. edulis) and oysters (Crassostrea gigas) [13].…”

A method for the determination of polybrominated diphenyl ethers (PBDEs) in aquatic animal tissue was developed, and it is based on cleanup by freezing-dispersive liquid-liquid microextraction (DLLME) for the pretreatment of samples with fat content. Aquatic animal tissue homogenate was extracted with acetone, and then frozen in a freezer at À801C. Fat in aquatic animal tissue was isolated from the analytes, i.e. PBDE congeners dissolved in acetone and fat formed floccules at low temperature. The supernatant was extracted using the DLLME technique. Under the optimum DLLME conditions, 0.75 mL supernatant with 33 mL chlorobenzene was added into 5.0 mL pure water, and subsequently cloudy solution was formed. After centrifuging, 1.0 mL lower phase was subjected to GC-MS analysis. Recovery test was performed at fortified concentrations of 5.0-2500 mg/kg. The detection results showed that the recoveries for each target analyte ranged from 75.3 to 127.8%. The repeatability of the proposed method by spiking aquatic animal samples at 10 mg/kg for PBDEs, expressed as RSD, n 5 5, varied between 4.3 and 10.3% (n 5 5). LOD of the proposed method for aquatic animal tissue samples were between 2.4 and 4.9 mg/kg for all the analytes.
