✦ Synopsis

Aquaria containing clean sand received a continuous supply of seawater from Santa Rosa Sound, Florida, USA, ~ mixed with known concentrations (7, 76 and 622 ~g 1-I) of pentachlorophenol (PCP). After 9 weeks, nematodes accounted for 87% of the total meiofauna. Nematode biomass and densities were greatest in aquaria exposed to 76 ~g PCP 1-I and were least in aquaria exposed to 622 ~g PCP 1-I. Epistrate feeders were abundant in control aquaria and aquaria exposed to 7 and 76 ~g PCP 1-I, but not in aquaria exposed to 622 ~g PCP 1 -I 9 Selective deposit feeders were not abundant in the control aquaria and aquaria exposed to 7 ~g PCP 1 -I , but comprised 19% of the nematodes in aquaria exposed :to 76 ~g PCP 1-I and 61% in aquaria exposed to 622 ~g PCP 1-I. ~ , . .
