Chlorinated water linked to rectal and bladder cancers
The straits times, Thursday, July 2, 1992
WASHINGTON-Chlorine, the chemical used to purify most of the US water supply, produced chemical by-products that caused a significant number of cases of rectal and bladder cancers each year, medical researchers said on Tuesday.
At least 18 per cent of rectal cancers (about 6,500 cases a year), and 9 per cent of bladder cancers (about 4,200 cases a year), could be linked to drinking, bathing and showering in chlorinated water, they wrote in the American Journal of Public Health.
It has been known since 1974 that chlorine combines with other organic compounds in water to form dangerous chemicals, among them is chloroform. Several studies have implicated these by-products as causes of cancer.
Dr. Robert Morris and colleagues reached their conclusions after examining 10 previous studies on the cancers-causing ability of chlorinated water.
Dr. Morris cited "... there is a clear pattern between consumption of chlorinated water with rectal and bladder cancers." The study was conducted at the Medical College of Wisconsin, where he is an epidemiologist, and at the Harvard School of Public Health.
Public water supplies depend on chlorine to kill disease-causing bacteria and to keep it pure in storage tanks and pipes. About 3/4 of the water supply in the US is chlorinated. However, the authors and other experts stressed that the new study should not lead to stopping chlorination.
"The potential health risks of microbial contamination of drinking water greatly exceed the risks of cancer", the author said.

Bahan cemar tinggi dalam air paip di Perlis, K'tan | ||
|
Kandungan bahan asing seperti klorin, bakteria E. coli, aluminium dan besi didapati tinggi dalam air terawat di Kelantan dan Perlis. Menurut Laporan Ketua Audit Negara 2008, ujian makmal yang dijalankan di Loji Rawatan Air (LRA) Pintu Geng, Kota Bharu mendapati kandungan besi dalam air terawat di loji itu adalah sangat ketara iaitu melebihi 0.3 miligram per liter. Sebagai contoh, pada Februari 2009, sebanyak 20 kali sehari ujian yang dilakukan mendapati kandungan besi dalam air dirawat ialah antara 1.5 hingga 1.8 miligram per liter setiap hari. Ujian yang dijalankan Kementerian Kesihatan terhadap kualiti air minum di Perlis pula menunjukkan terdapat 7.1 peratus klorin, 6.8 peratus E. coli dan 4.1 peratus aluminium di dalam air itu. "Kekerapan ujian di loji yang dijalankan hanyalah antara lima dan enam kali sehari tidak memadai bagi memastikan tahap kualiti air yang dibekalkan pada pengguna adalah selamat," kata laporan itu. Selain itu, Jabatan Pengairan dan Saliran Perlis tidak membuat ujian di stesen pensampelan yang menyebabkan keputusan pensampelan hanya bergantung kepada ujian yang dijalankan pihak Jabatan Kesihatan. Menurut laporan itu, bagi meningkatkan kualiti air minum yang dibekalkan, pihak terbabit disyor supaya menyegerakan perwartaan kawasan tadahan, muka sauk, medan telaga dan LRA sebagai kawasan larangan, selain menaiktaraf LRA. Tindakan penambahbaikan dari segi kekerapan ujian dan membaiki stesen pensampelan yang rosak dengan segera, turut menjamin tahap kualiti air yang dibekalkan. BERNAMA |
