“…Lead exposure is arguably the oldest known occupational health hazard. It is a particularly insidious hazard with the potential for causing irreversible health effects, including hypotension, central nervous system problems, anemia and diminished hearing acuity before it is clinically recognized (Pagliuca & Mufti 1990;Hu 2000). Similar to other developing countries, lead pollution becomes an important public health problem of Thailand, especially for the big cities as Bangkok.…”

“…Lead exposure must be of particular concern because of ongoing exposure to thousands of workers in the industrial plants and recent research indicating that asymptomatic lead exposure can result in chronic toxicity manifestations, such as hypertension, kidney impairment, and cognitive disturbances (Pagliuca & Mufti 1990). Its toxicity correlates with blood concentrations and progresses from biochemical and subclinical abnormalities at levels around 100 lg/l to coma and death at levels over 1,000 lg/l (Markowitz 2000).…”

Lead is an important toxic metal found in industrial communities. Due to the industrialization in the recent decade in Thailand, lead intoxication as a toxicant-related disorder becomes a new public health problem. A retrospective study on clinical presentation of hospitalized patients with diagnosis of lead intoxication during year 1990-1999 in King Chulalongkorn Memorial hospital, the largest Thai Red Cross Society Hospital, was performed. All 14 cases diagnosed with lead intoxication were identified in our series. Average age of the subjects was 25.55 +/- 21.93 years old. Male predominance was detected in our series (male:female = 12:2). Two main groups of subjects as; (1) childhood aged below 10 years old (male:female = 4:2) and (2) adult aged between 24 and 60 years old (n = 8, all male), can be identified. For the first group, the clinical presentations were convulsion (n = 3), unexplained anemia (n = 1), attention deficit (n = 1) and asymptomatic (n = 1), respectively. All of the subjects in this group presented the history of living at the old battery plant area. Five of the six cases came from the same village. For the second group, the clinical presentations were unexplained abdominal pain (n = 5), chronic renal failure (n = 1), unexplained anemia (n = 1) and asymptomatic (n = 1), respectively. Most of the subjects (75%) in this group presented the history of working in the battery plant for more than 10 years. Another case presented the history of gunshot and residual bullet in the bone marrow. The other one left is an interesting case with the history of prolonged usage of ritual pill and holy paper incineration. Like other studies, battery plant had strong relation with the lead intoxication. Although the total identified cases are rather few, there may be more undetected asymptomatic lead intoxication cases in the community. Specific control of lead resulted from battery plant and monitoring of the workers as public health strategies are still recommended.

ABSTRAKKandungan logam berat yang terdapat dalam jumlah yang kecil di perairan dibutuhkan oleh makhluk hidup, tetapi dalam jumlah besar dapat menyebabkan berbagai masalah. Kehadiran industri berperan dalam meningkatkan cemaran logam berat. Berbagai cara telah dilakukan untuk mengurangi cemaran logam berat. Metode adsorbsi adalah cara yang banyak digunakan untuk mengurangi cemaran logam berat, karena aplikasinya yang cukup luas untuk berbagai jenis logam berat. Beberapa bahan alami yang ramah lingkungan seperti kitosan dan selulosa dapat digunakan sebagai adsorben. Baik kitosan maupun selulosa harus melewati tahap modifikasi untuk meningkatkan efektifitasnya sebelum digunakan sebagai adsorben.

Heavy metal waste streams from a variety of industrial sources pose a significant environmental threat to receiving waters. Significant research work has focused on the use of adsorbents and adsorption in the treatment and recovery of these metals from waste streams. This paper focuses specifically on the design of a novel adsorbent based on the naturally occurring material, cellulose and application of this novel material to the removal of selected heavy metals from waste streams. Cellulose material has limited heavy metal adsorbing capability. To enhance its sorption capacity, a sorbent material was prepared by firstly grafting glycidyl methacrylate monomer to cellulose. The grafted product was then functionalised by the addition of imidazole. The novel material was then assessed for its ability to adsorb the heavy metals Cu(II), Ni(II) and Pb(II). Uptake levels on the cellulose-g-GMA-imidazole material were 68 mg g -1 Cu(II), 45 mg g -1 Ni(II), 71 mg g -1 Pb(II). These uptake levels compared favourably with those achieved using other naturally occurring materials. The level of uptake of each metal on the modified cellulose material was found, in all cases, to be significantly influenced by aqueous pH. The optimum pH range in all cases ranged from approximately pH 4 to pH 5.5. The speed of uptake of each metal on the sorbent material ranged from approximately 40 minutes in the case of Cu(II) and Pb(II) to almost 400 minutes for Ni(II) depending on initial metal concentration in solution. The overall kinetics in each case is best described by the pseudo-second order approach. Almost complete recovery of each metal from the modified cellulose material was possible using a 0.1M acid solution; however, re-use of the sorbent materials in further adsorption cycles yielded variable outcomes.
