trace element content and potential human health risk from consumption of the deep-water rose shrimp parapenaeus longirostris (crustacea: decapoda) from pagasitikos gulf, greece

The content of as, cd, cr, cu, fe, mn, ni, pb, and zn as the whole-body burden and the content of cd and pb in muscle tissue of parapenaeus longirostris, were evaluated in shrimp collected from the pagasitikos gulf, greece. the whole-body burden of fe was 102 ± 39, mn 71 ± 23, as 64 ± 33, zn 62 ± 8, cu 34 ± 16, ni 4.6 ± 2.9, cr 1.01 ± 0.39, cd 0.93 ± 0.33 and pb 0.88 ± 0.47 ppm wet weight. muscle tissue content for cd was 0.47 ± 0.08 and for pb 0.31 ± 0.06 ppm wet weight. the estimation of weekly intakes and target hazard quotients for the potentially toxic elements cd and pb revealed that rose shrimp from pagasitikos gulf could be considered safe for human consumption, probably with a general advisory to avoid the consumption of anything other than the muscle tissue.
