Chemical contamination and toxicity of sediment from a coastal area receiving industrial effluents in Kuwait.

The Shuaiba coastal area (12.5 x 1.5 km) was examined for contamination with total organic carbon, volatile organic matter, total petroleum hydrocarbons, polycyclic aromatic hydrocarbons, cadmium, chromium, copper, lead, nickel, vanadium, and zinc in sediment; their desorption by aqueous elution; and toxicity to aquatic biota. The pollutants were mainly accumulated in the upstream area facing Mina Al-Ahmadi refinery to Shuaiba harbour. Solid-phase Microtox assays showed severe toxicity, and the LC(50) was negatively correlated with most of the chemical parameters, suggesting that toxicity was the function of collective effects of the pollutants present in sediment. Sea water elutriation showed poor desorption of pollutants from sediment, and the elutriates were not found toxic to Microtox and brine shrimp larvae. Whole sediment suspension in sea water reduced the survival of fingerlings in fish bioassays. Action from Shuaiba Area Authority is required to reduce pollutant accumulation in identified depositional area on the Shuaiba coast by facilitating unrestricted water flow in the area and restricting pollutant discharge at source.

Outcome of referrals to a district immunisation advisory clinic.

We have studied referrals to and outcomes of consultation at a district immunisation advisory clinic, aiming to examine and confirm the rarity of true contraindications, the safety of immunising children with possible contraindications, and the influence on parents of counselling by well informed professionals. We examined medical records and postal questionnaires to parents, representing 30 months' work. Three hundred and fifty-eight children were referred to the clinic, 248 of whom were seen and 110 (31%) did not attend. Fourteen children who attended (6%) had a true contraindication to the vaccine(s) in question and 202 of the remaining 234 (86%) proceeded to vaccination with no adverse effect. Forty of the 110 (36%) who were referred but did not attend were vaccinated, and no adverse effects were reported, but the immunisation rate of this group was significantly lower than that seen in the clinic (chi 2 test, p < 0.001). True contraindications to childhood immunisation were rare, and children with difficult problems were safely vaccinated. The immunisation advisory clinic is effective in counselling parents who are uncertain about childhood immunisation.

False contraindications to childhood immunization.

An immunization advisory clinic was set up in mid-Essex in 1988 to provide a referral facility for professionals and parents who were unsure about the eligibility of certain children to receive immunization. This paper describes four typical cases. The history and management of each case are described and the fact that all the children were successfully immunized is highlighted. It is hoped that by sharing the experiences of the immunization advisory clinic with other professional staff, more positive decisions regarding immunizations will be made.
