Developments in Health-Related Quality Standards for Chemicals in Drinking Water

Small differences in water quality standards can mean huge differences in costs for water treatment; difficulties which are compounded by standards for which the derivation is unclear, such as the EC drinking water Directive. Such situations give no indication of the margin of safety for a parameter or the significance to consumers of exceedances. The WHO Guidelines are being revised and will be presented so that the precise derivation of the numbers is absolutely clear. The scientific and quasi-scientific considerations can be separated and the user given the appropriate information to adapt the guidelines to particular circumstances. In deriving standards for toxicological data the factors incorporated reflect uncertainties in the data and extrapolation from animals to man. Understanding the mechanisms of toxicity or carcinogenicity can reduce the uncertainty and improve the quality of the standard, often allowing higher figures to be used with confidence that public health will not be comprised.     

Dampness in buildings and health. Nordic interdisciplinary review of the scientific evidence on associations between exposure to "dampness" in buildings and health effects (NORDDAMP)

Several epidemiological investigations concerning indoor environments have indicated that "dampness" in buildings is associated to health effects such as respiratory symptoms, asthma and allergy. The aim of the present interdisciplinary review is to evaluate this association as shown in the epidemiological literature. A literature search identified 590 peer-reviewed articles of which 61 have been the foundation for this review. The review shows that "dampness" in buildings appears to increase the risk for health effects in the airways, such as cough, wheeze and asthma. Relative risks are in the range of OR 1.4-2.2. There also seems to be an association between "dampness" and other symptoms such as tiredness, headache and airways infections. It is concluded that the evidence for a causal association between "dampness" and health effects is strong. However, the mechanisms are unknown. Several definitions of dampness have been used in the studies, but all seems to be associated with health problems. Sensitisation to mites may be one but obviously not the only mechanism. Even if the mechanisms are unknown, there is sufficient evidence to take preventive measures against dampness in buildings.     

超高效液相色谱-二极管阵列检测法测定油基类保健食品中的维生素K2的含量

建立了超高效液相色谱-二极管阵列检测法(UPLC-PDA)测定油基类保健食品中维生素K 2(七烯甲萘醌)含量的方法。试验显示维生素K 2对紫外光、强碱条件敏感。样品经脂肪酶酶解后,皂化、萃取、复溶,C 18色谱柱(100×2.1 mm,1.7μm)分离,甲醇为流动相,流速为0.3 mL/min,254 nm检测。本法在1.0~20.0 mg/L线性关系良好,R 2=0.9999。当取样量为1 g,定容至10 mL时,方法LOD为1μg/g,LOQ为3μg/g,RSD为1.2%,加标回收率为98.7%~102.2%。该法准确、高效,对各类保健食品具有良好的普适性。     

贫化铀的环境污染影响及其对人体健康的危害

贫化铀是铀富集过程中产生的副产品。由于其独特的物理特性,被广泛开发利用到民用和军事用途。“海湾战争综合症”和“巴尔干综合症”引起了人们对贫铀使用后,对环境污染的影响和对人体健康效应研究的重视。贫铀的危害来自化学毒性和放射性毒性两个方面。由于贫铀的放射性比活度低,而且主要发射α粒子,所以来自贫铀的辐射伤害主要是吸入贫铀气溶胶后对肺和其他器官较长时间的内照射。     

A comparative study of trends of nitrate,chloride and phosphate concentration levels in selected urban rivers

Concerns for the river environment in Malaysia are highlighted. There had been occurrences of inadequate supply for water in big cities and unexpected floods over the last few years. This paper discussed and compared the results of efforts to clean-up Gombak River which passes through several industrial areas and the City of Kuala Lumpur and Penchala River which passes through the industrial areas and the neighboring City of Petaling Jaya. The trends in the levels of nitrates, chlorides and phosphates present in the rivers were analyzed. Over the period of thirteen years from 1997 to 2009, results of efforts which included public participation, engineering and river works and strict statutory regulations by government had shown success in improving the river water quality. Continued efforts from stakeholders must be harnessed to enhance the health of the Gombak River and the Penchala River.     

Correlates of motorcycle helmet use among recent graduates of a motorcycle training course

Helmets significantly decrease morbidity and mortality from motorcycle crashes, but many areas of the world lack universal helmet laws. To educate motorcyclists in areas without helmet laws, more knowledge of motorcyclists’ helmet beliefs is needed.A web-based survey was therefore designed to assess motorcyclists’ attitudes, norms and behaviors towards helmets in a U.S. state with a limited helmet law. Of 445 survey respondents, 68.4% of respondents reported always wearing a helmet. The not-always-helmeted riders were more likely than the always-helmeted to be male; to bave less education; and to have a history of previous motorcycle crashes and injuries. Although both groups had taken rider training classes, fewer of the not-always-helmeted had learned how to ride in a class. The strongest correlates of being not-always-helmeted (vs. always-helmeted) were attitudes that helmets were not protective and impaired sight/hearing; and the normative belief that they would only wear helmets if forced by law. Because attitudes are often more easily changed than normative beliefs, education may increase helmet use. However, less than half of riders in this state with a mandatory education program learned how to ride from a rider education course, and 44% of non-helmeted said they would only wear a helmet if forced by law. Legislation may therefore be a more efficient and effective strategy than education to increase helmet use.
