Several investigators demonstrated that tolerance to pollutants can be increased by previous exposure to low sublethal concentrations. Acquired tolerance to metal can result from increased synthesis of metallothioneins. Metallothioneins are small (6000-7000 daltons), sulphydryl-rich, metal binding proteins, whose free thiol groups readily bind the heavy metals. The purpose of the present study was to investigate the effect of pre-treatment with low doses of cadmium chloride (Cd) and mercuric chloride (Hg) on tolerance to higher levels of cadmium to two populations of grass shrimp, Palaemonentes pugio. One was from Piles Creek (PC), a tributary of the Arthur Kill in heavily industrialized Linden, New Jerseys. The other populations was from Big Sheepshead Creek (BSC), a relatively pristine system near non-industrialized Tuckerton, New Jersey. Piles Creek sediment metal concentrations have been reported to be 11.2, 5.9, 623.4, and 627.9 ug/g of Hg, Cd, Cu, and Zn, respectively; whereas BSC sediment contained 0.054, 0.13, 12.9, and 7.7 ug/g of Hg, Cd, Cu, and Zn respectively.
