“…Mean ΣDDT concentrations in the fat of lesser yellowlegs and semipalmated plovers ranged from 3.3 and 5.0 μg g −1 , respectively, in the unsprayed areas to 20 and 52 μg g −1 , respectively, in the sprayed area (Brown and Brown 1970). Given that the field half-life of DDT is 2-15 years (Augustijn-Beckers et al 1994), one could reasonably expect the effects of the spraying to remain detectable in the environment even after several decades. Therefore, the choice of feeding location around Cape Churchill may have had an effect on the ΣDDT levels found in the birds, and may provide a partial explanation for the wide range of concentrations (0.25-29 μg g −1 ) found ( Table 2).…”

Canadian shorebirds are exposed to environmental contaminants throughout their annual cycle. Contaminant exposure among species varies with diet, foraging behaviour and migration patterns. We sampled twelve species of shorebirds from four locations across Canada to assess their exposure to PCBs, organochlorine pesticides, as well as four trace elements (Hg, Se, Cd, As). SigmaPCB and SigmaDDT followed by SigmaCHL were most frequently found above trace level in the shorebird carcasses. In general, the plover species (American golden, semipalmated, black-bellied) appear to be the most contaminated with organochlorines, whereas Hudsonian and marbled godwits appear to be the least contaminated. Among adult birds, the greater and lesser yellowlegs had the highest hepatic Hg concentrations (2.4-2.7 microg g(-1) dw), whereas American golden plovers as well as Hudsonian and marbled godwits contained relatively low levels of Hg (<1 microg g(-1) dw). Renal Se concentrations varied from 3.2 to 16.7 microg g(-1) dw and exhibited little interspecific or seasonal variation. Renal Cd levels in adult birds were highest in Hudsonian godwits from Quill Lakes (43 microg g(-1) dw) and Cape Churchill (12 microg g(-1) dw), and lowest (0.8-1.5 microg g(-1) dw) in greater and lesser yellowlegs from Cape Churchill and Bay of Fundy. Renal As concentrations varied from 0.06 microg g(-1) dw in golden plovers from Cape Churchill to 4.6 and 5.1 microg g(-1) dw in dunlin samples from the Pacific coast. There is no evidence that contaminants were adversely affecting the shorebirds sampled from the Canadian locations in this study.

“…Pesticide properties including water solubility were derived from Tomlin (2000). Degradation rates of pesticides in paddy water and sediment were derived from literature half life values assuming first-order decay (Wauchope et al 1992;Augustijn-Beckers et al 1994;Barefoot et al 1996;Jackson and Douglas 1999;US EPA 2003;Vidotto et al 2004) (Table 4). Degradation rates for paddy water and sediment which are essential for the parameterization of RICEWQ were derived from degradation studies in aerobic water/sediment systems in accordance to Med-Rice recommendations.…”

“…Finally, half-life values from aerobic soil studies were utilized for calculating degradation rates in the other two soil layers (30-60 and 60-100 cm). Adsorption coefficients K d for each pesticide were separately calculated for clay and sandy Med-Rice scenarios by their respective literature organic carbon adsorption coefficients, K oc (Wauchope et al 1992;Augustijn-Beckers et al 1994;Barefoot et al 1996;Jackson and Douglas 1999;Tomlin 2000;Lozzi et al 2003) with the following equation:…”

Rice is commonly cultivated in Southern Europe in large river basins where the extensive use of herbicides may impact water quality at basin scale level. Consequently, pesticide risk assessment would be more relevant when considering a rice cultivation area as a whole. Accordingly, two watershed-scale scenarios were developed to represent the specific agronomic, water and pesticide management practices of rice cultivation in Greece. These scenarios were utilized for the parameterization of the rice water quality model (RICEWQ) 1.6.2v and the surface water model river water quality (RIVWQ) 2.02. in order to predict the environmental concentrations of pesticides in groundwater (GW) and surface water (SW) systems within a rice area. The annual average pesticide concentrations at 1 m depth, predicted by RICEWQ were used to assess the risk for GW contamination. The predicted exposure concentrations derived through modelling and eco-toxicological endpoints obtained from the literature, were used to calculate acute and long-term toxicity exposure ratios (TERs) for aquatic organisms. Application of these scenarios with RICEWQ and RIVWQ models enabled us to perform a risk assessment exercise for several herbicides registered in Greece for use in rice. Such a risk assessment approach could be further scaled up to represent a whole rice cultivated basin in order to be used for regulatory purposes.

“…6 In soil, PCP is moderately persistent with a reported field half-life of 45 days. 9 The sorption of PCP is strongly dependent on the pH conditions of the surrounding medium and increases with higher proportions of organic matter. Under neutral or alkaline conditions, PCP is poorly adsorbed and is mobile in many soils.…”

Phenolic compounds are widely distributed in our ecosystems. In addition to naturally occurring phenols, the majority of toxic phenolic substances are released into the environment by industry and agriculture. As the manufacture and use of phenols requires qualitative and quantitative control, a wide variety of methods have been developed to determine phenolic compounds. In addition to coarse screening to rapidly obtain a general overview, many highly specialized techniques exist that are geared to individual analysis problems. The range of available methods extends from steam distillation and classic liquid–liquid extraction (LLE) as sample preparation combined with photometric or ultraviolet (UV) detection, to more sophisticated techniques such as liquid–solid extraction (LSE) including solid‐phase extraction (SPE) and solid‐phase microextraction (SPME) coupled to gas chromatography/mass spectrometry (GC/MS) and high‐performance liquid chromatography/mass spectrometry (HPLC/MS). This article describes the most suitable methods, taking account of special factors such as substance class, chemical properties, concentration range and accompanying matrices. Some new trends in phenol determination are also discussed in comparison with the established methods. The basic factors governing the selection of suitable analysis methods are also covered.
