Water safety statistics

Numerical quantities, experimentally determined or estimated by statistical or computational approaches, which measure the environmental behavior, fate, and toxicity of chemicals, are molecular descriptors usually referred to as environmental indices. The octanol-water partition coefficient (Kqw, log P) is the most well-known environmental index used as the measure of lipophilicity of compounds. Together with log P and the soil sorption partition coefficient (Koc) [Baker, Mihelcic et al, 2001 Uddameri and Kuchanur, 2004], other quantities have to be considered as relevant for environmental studies. Some of these have been defined to describe mobility, biodegradabUity, bioaccumulation, metabolism, partition, and toxicity of chemicals, thus becoming relevant to human health and environmental safety assessment. 

I2 reacts with water to yield a complex mixture of iodine species including iodide, iodate and triiodide, and this complicates the evaluation of safety data from this trial. The total dose of iodine provided to these patients probably exceeded the estimated upper limit of 5 mg/day. Symptoms associated with hyper- or hypothyroidism were observed, but no statistically significant differences... 

A nonprofit association of insurance companies that provides services for participating companies. It provides statistical, actuarial, and underwriting information for numerous affiliated insurance companies and more than a dozen lines of insurance. It maintains one of the largest private databases in the world for insurance premiums and losses paid. Included in these lines is liability, automobile, boiler and machinery, homeowners, farm, and commercial fire insurance. ISO is a voluntary, nonprofit, unincorporated association of insurers. Previous to 1971, the functions performed by ISO were undertaken by various insurance organizations in different states. ISO gathers data that are used to establish rates for fire protection policies for residential and commercial properties. ISO developed the municipal grading schedule, which is commonly used to establish a basis of insurance rates for municipalities. It is an evaluation of the fire protection features of cities and towns based on seven factors climatic conditions, water supply, fire department, fire service communications, fire safety control, building codes, and a survey report.

The marine accident statistics produced in this paper, are based on the data from winters December 2002 to April 2003 and October 2009 to April 2013. The data sources used for this analysis are provided by the Finnish Transport Safety Agency (Trafi), which consist of marine casualties reported on Finnish waters or to vessels registered to Finland. In the particular case of the reports from winters 2009-2013, identification of the accident locations is based on the coordinates of the accidents reported in that time period. And for the purposes of this paper, those coordinates have been allocated within the ice maps reported by SMHI and FMI on those dates. More details such as the kind of vessel involved in the accidents. 

ABSTRACT In the definition of safety states of water supply system the quality of drinking water plays an important role. Especially, trihalomethanes as disinfection by-products have to be taken into consideration, because they are dangerous for consumer s health and their concentration usually increase in water distribution subsystem. In this paper the method of determining the thresholds for water quality states (included in the comprehensive method of safety analysis) is presented. The states are based on chloroform because its share in total trihalomethanes is about 80%. Using the tools of mathematical statistics the relationships between chloroform and other quality and operational parameters of drinking water were analyzed and applied to an estimation of quality states. Additionally, the estimation of quality states was based on chloroform in drinking water flowing out from water treatment plant to water pipe network. The study was based on data obtained from the real water supply system.
