Assessment of household use of iodized salt and adequacy of salt iodization: a cross-sectional National Study in Saudi Arabia.

Objectives: This study was conducted to assess household coverage with iodized salt in Saudi Arabia, and to determine adequacy of salt iodization.

Methods: A school-based cross-sectional study using WHO 30-cluster survey methodology.

Results: Analysis of 4242 salt samples using qualitative rapid test kit (RTK) revealed that 68.

Prevalence of iodine deficiency disorders among school children in Saudi Arabia: results of a national iodine nutrition study.

This study aimed at establishing updated data on iodine nutrition among schoolchildren in Saudi Arabia. A cross-sectional cluster survey among schoolchildren aged 8-10 years was conducted during February-April 2012. Children were clinically examined for goitre, urine and household salt samples were collected to estimate urinary iodine concenteration (UIC) and iodine content in salt.

Adsorption of phenol by bentonite.

The potential of bentonite for phenol adsorption from aqueous solutions was studied. Batch kinetics and isotherm studies were carried out to evaluate the effect of contact time, initial concentration, pH, presence of solvent, and the desorption characteristics of bentonite. The adsorption of phenol increases with increasing initial phenol concentration and decreases with increasing the solution pH value.

A review of some statistics on breastfeeding in Saudi Arabia.

Breastfeeding is the ideal and most natural way of nurturing infants. The importance of breastfeeding has been proved unequivocally, and UNICEF and WHO have issued guidelines to ensure breastfeeding. Saudi Arabia is a country where the legislation is derived from the Quran and Hadiths.

Effect of soil/contaminant interactions on the biodegradation of naphthalene in flooded soil under denitrifying conditions.

The mineralization of 14C-labelled naphthalene was studied in pristine and oil-contaminated soil slurry (30% solids) under denitrifying conditions using a range of concentrations from below to above the aqueous phase saturation level. Results from sorption-desorption experiments indicated that naphthalene desorption was highly irreversible and decreased with an increase in the soil organic content, thus influencing the availability for microbial consumption. Under denitrifying conditions, the mineralization of naphthalene to CO2 occurred in parallel with the consumption of nitrate and an increase in pH from 7.
