“…In addition, previous studies have pointed out the enrichment of heavy metals in muscle, gills, liver, and kidney of fish (Fazio et al, 2014;Svecevicius et al, 2014;Wei et al, 2014). The NPs enhance the uptake heavy metal and organic toxicants (Baun et al, 2008;Tan et al, 2012;Wang et al, 2012Wang et al, , 2014.…”

“…Heavy metals are stable, persistent, nonbiodegradable, and toxic contaminants of aquatic environments, and they can accumulate in organisms and food chains, therefore potentially threatening the health of aquatic organisms (Wu et al, 2013a,b) and human beings (Papagiannis et al, 2004). Heavy metal contaminations caused by industrialization, urbanization, and agricultural activities are increasing in aquatic environments, and it has become a serious issue worldwide (Tarras et al, 2001;Cheng, 2003;Malik et al, 2010), Many researchers have made efforts to determine heavy metal concentrations in aquatic environments and aquatic organisms, and to investigate the potential health risk of heavy metals to consumers caused by consumption of contaminated seafood (Copat et al, 2013;Li et al, 2013;Wei et al, 2014). Owing to the effects of bioaccumulation and biomagnification, some heavy metals with low concentrations could rise to hazardous levels through food chains in aquatic organisms (Castro and Mendez, 2008;Qiu et al, 2011).…”

“…The replicate numbers of the sample for each site was six (six clams). In this study, heavy metal concentrations were obtained as wet weight (lg g À1 ) with the water content assumed to be 80% (Usero et al, 2005;Wei et al, 2014).…”

a b s t r a c tTo investigate the pollution level and evaluate the potential health risks of heavy metals, the concentrations of chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), molybdenum (Mo), cadmium (Cd), antimony (Sb), and lead (Pb) were determined by inductively coupled plasma-mass spectrometry (ICP-MS) in 198 clams (Mactra veneriformis) collected from 11 sites of the Bohai Bay. The results showed that heavy metal concentrations in the clams were different at different sites (p < 0.05). Mn was dominant with a percentage of 22.08-77.03% in heavy metals, followed by Zn with 12.66-57.11%, and the concentration of Pb was the lowest with 0.45-1.04%. The potential health risk to consumers was evaluated by the target hazard quotient (THQ) and the maximum daily consumption rate (CR max ). The results indicated that the THQs of Co were the highest with the values of 1.125, 1.665, and 1.144 at three sections; the values of other individual metals were <1, which indicated that consumption of clams from the study areas caused health risks due to Co. Moreover, the CR max values also indicated the potential health risk caused by Co in clams consumed in this area. Pearson correlation analysis and principal component analysis (PCA) indicated that there were significantly positive or negative correlations between the heavy metals (p < 0.05), and the studied metals were divided into four groups. The results indicated that the concentrations of heavy metals in clams were affected not only by pollution sources but also by the characteristics of clams that could absorb selectively and accumulate special metals. This study offers important information on the pollution levels of heavy metals in clams and warns consumers of the health risks associated with the consumption of clams in the area.

“…The area of Poyang Lake Wetland is about 2698 km 2 [4]. It is the largest and the most important freshwater wetland in China [5,6]. Poyang Lake Wetland plays an irreplaceable ecological role in flood storage and biodiversity conservation, so much so that it is credited with the maintenance of regional, and even, national ecological security.…”

Determinants of Farmers’ Willingness to Pay and Its Level for Ecological Compensation of Poyang Lake Wetland, China: A Household-Level Survey

2014

View full text Add to dashboard Cite

This study examines the determinants of farmers' willingness to pay (WTP) and their payment levels for ecological compensation of the Poyang Lake Wetland in China. We developed a farmer household survey and gathered 292 effective responses. The contingent valuation method (CVM) and Heckman's two-step model were employed for the empirical study. Results show that 46.58% of farmers are willing to pay ecological compensation, with an average price of $64.39/household per year. The influencing factors that significantly influence farmers' WTP include household income, residential location, emphasis on improvement of wetland resources, arable land area, and contracted water area. In addition, household income, residential location, arable land area, and contracted water area are significantly related to their payment levels. The results of this empirical study inform important policy implications and recommendations.
