In Finland, the most important dietary source of PCDD/Fs and PCBs is fish, contributing 95 and 80% of total dietary intake, respectively, and for PBDEs, the contribution of fish is much lower (55%) and other sources are more diverse (12).
Since in silico BCF models often neglect the contribution of fish metabolism as a clearance mechanism, they might overestimate the bioaccumulative potential of a chemical and, as a consequence, trigger unnecessary in vivo tests.
The contribution of fish to global diets is increasing (17 kg cap 1 yr–1 in 2008).
Data showing fish consumption rates in SIDS, and the contribution of fish to the overall protein intake, are shown in Table 3.
Because of low fish consumption (1.2 g/day/person) (BGS 2007) and low Hg concentrations (Table 1), the contribution of fish to the Hg intake is low (1 2%).
Although the full range of items contributing to the diet of the examined terapontids have been quantified (22 different food classes [ 40]), in this study, gut contents were simply categorised as the percent contribution of animal material to species' diet (i.e., the combined contribution of fish, insects and crustaceans).
Additional analyses of patterns of fish consumption incorporating analyses of the levels of contamination in various fish species from the contaminated waters would further refine our understanding of the contributions of fish contaminants to serum dioxin levels.
Since the 1990s the government has supported the agricultural sector with subsidies and low-interest loans, but the overall contribution of agriculture, fishing, and forestry to the GDP has further decreased.
Its gross state product is less than $50 billion, and the contribution of hunting, fishing, bird-watching, boating and so on is put at $2.5 billion—a vital statistic in a state where L.L. Bean, an outdoors catalogue company, ranks among the five largest employers.
In severely feminized fish, fertility is reduced (Jobling et al. 2002b); hence, the contribution of these fish to the growth rate of the population is likely to be reduced.
