This paper has given a study on the up-to-date advances in exposure situation of human body to boron. As is known, boron is a ubiquitous element in nature. The range of boron concentration in the soil is about 2-100 mg/kg on average of 20 mg/kg. The average concentration of boron in the sea water is 4.6mg/L, while its range of concentration is from 0.01 to 1.5 mg/L in fresh water. Since common people are exposed to boron mainly through drinking water and eating food, daily boron intake for average people is about 0.2-0.6 mg/d usually through drinking water, and about 1-2 mg/d through food. However, boron occupational workers are exposed more seriously to boron by air intake, though the degrees of their exposure also differ as the different boron levels in air particulars. The half-life of boron metabolism in human body is less than 24 h and its excretion is mainly done through urine. After being absorbed, boron is distributed in human-body liquid quickly. Its level in bone is proves higher than that in blood. Its concentration in urine of normal people is about 1 μg/mL, while in blood, boron concentration ranges from scores of nanograms to 100 nanograms per microlitre. However, its concentrations in urine and blood of people under high boron exposure can be much higher. Nevertheless, boron exposure level can be estimated properly. Therefore, it can be used as a biomarker. The present paper has made a summary on boron exposure through different approaches and from the point of view of its metabolize catabolism and biomarker, and proposed further research highlights in the future through the given summary.
