“…This mortality rate is also close to those reported by Laskowski and Hopkin (1996b), who found, respectively, 6.7 and 1.9% mortality in subadult (about 4 months old) and adult H. aspersa snails exposed to Zn, Cu, Pb, and Cd (alone or in combination) in agar-based food. In agreement with these studies, results of the present study reveal that mortality cannot be considered a sensitive parameter for studying the harmful e!ects of environmental Cd pollution, over a 1-month period.…”

“…These authors also reported that growth reduction was closely correlated with the observed feeding rates (r"0.98). Moreover, Laskowski and Hopkin (1996b) reported consumption rates signi"cantly lower than control above 60 g)g\.…”

“…Whether food consumption reduction or a direct metal toxic e!ect is responsible for growth reduction is still unclear (Laskowski and Hopkin, 1996b;Gomot, 1997) although both are probably responsible for the e!ects observed under laboratory conditions. The group exposed to the highest Cd levels in the present experiment (177 g)g\) exhibited 43% growth reduction.…”

“…This concentration was higher than the maximum level of 0.5 ppm set by FAO (2001). However, the Pb level in the egg strings was lower compared to the study of Laskowski and Hopkin (1995) with Pb concentrations ranging from 21 to 156 mg/kg in H. adspersa and so with Aplysia californica with a range of 2.5 to 300 mg/kg. It is also shown that the Pb accumulation differs in the organs of sea hare, Aplysia californica after a metal dietary exposure (Jarvis et al, 2015).…”

The egg strings of sea hare, Dolabella auricularia are economically important to the local fisher folks in Davao Oriental. These are gathered for food consumption or sold in the market. The province of Davao Oriental is one of the country's tourist destinations. Increasing anthropogenic activities are inevitable which can contribute to the levels of trace metal concentrations in the area. The primary purpose of this study was to determine the concentrations of Fe, Zn, Cd, Hg and Pb using atomic absorption spectrophotometer. Trace metals average concentrations in egg strings were found to be 175.67 µg g -1 for Fe, 282.00 µg g -1 for Zn, 0.98 µg g -1 for Cd, 0.01 µg g -1 for Hg and 6.94 µg g -1 for Pb. The Fe and Zn concentrations can supplement the body's requirement needed for normal growth and development based on the Recommended Energy Nutrient Intakes for Filipinos. Moreover, the mercury concentration was lower than the existing standard set by FAO No. 21 of 2001. However, the amount of Cd and Pb were noticeably higher than the maximum level. This investigation represents the first study so far on the levels of trace metals in egg strings of sea hare from Pujada Bay, Davao Oriental. The results of this study provide baseline information for the conduct of further investigation to monitor and evaluate the trace metal concentrations and the contributing anthropogenic activities. These will help the local government in the formulation of policies for a sustainable development.

“…Nonetheless, ANOVA may be helpful in mixture analyses to demonstrate whether a chemical contributes to toxicity. For example, Laskowski and Hopkin (1996) compared EC50 values of zinc in the presence and absence of three other metals for the snail H. aspersa. The toxic effect of the mixture was stronger than that of zinc alone.…”
