“…Habes et al (2006) reported that diets amended with increasing doses of BA damaged epithelial cells and impaired antioxidant defense in midgut of Blatella germenica causing increased mortality. A similar mechanism has been suggested for various pest insects exposed to BA in different baits (Cochran, 1995).…”

Larvae of the wax moth, Galleria mellonella (L.), were reared from first instar on a diet supplemented with 156, 620, 1,250, or 2,500 ppm boric acid (BA). The content of malondialdehyde (MDA, an oxidative stress indicator), and activities of the antioxidant enzymes [superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), and glutathione peroxidase (GPx)] were determined in the fat body and hemolymph in the 7th instar larvae and newly emerged pupae. Relative to control larvae, MDA was significantly increased in larval hemolymph, larval and pupal fat body, but decreased in the pupal hemolymph. Insects reared on diets with 156- and 620-ppm BA doses yielded increased SOD activity but 1,250- and 2,500-ppm doses resulted in decreased SOD activity in larval hemolymph. SOD activity was significantly increased but CAT was decreased in the larval fat body. High dietary BA treatments led to significantly decreased GST activity. However, they increased GPx activity in larval hemolymph. Dietary BA also affected larval survival. The 1,250- and 2,500-ppm concentrations led to significantly increased larval and pupal mortality and prolonged development. In contrast, the lowest BA concentration increased longevity and shortened development. We infer that BA toxicity is related, at least in part, to oxidative stress management.

“…Based on a histological study of the digestive tract of B. germanica after ingestion of boric acid, Cochran (1995b) concluded that destruction of the foregut epithelium might result in death from starvation. This is unlikely, however, because cockroaches exposed to boric acid die much faster than starved cockroaches (C. Schal, personal observation).…”

“…The mode of action of boric acid against insects is unknown, although destruction of the digestive tract wall and penetration of the exoskeleton have been reported (Ebeling, 1995). Cochran (1995b) reported that boric acid destroys the foregut epithelium and suggested that cockroaches might die from starvation. Boric acid has a very good safety record for mammals; it does not volatilize (in contrast to organic insecticides) and absorption of boric acid through unbroken skin is negligible (Pfeiffer, 1951;Valdes-Dupena and Arey, 1962;Ebeling, 1995).…”

“…Recently, boron has extensively been used in a wide variety of industries, i.e., insecticides (14), food preservatives, fire retardants (15), glass products (16), detergents (17), semiconductors in electrical applications and reagents for chemical synthesis. Important boron sources are rasorite (kernite) and tincal (borax ore).…”

The biological, medical and environmental roles of trace elements have attracted considerable attention over the years. In spite of their relevance in nutritional, occupational and toxicological aspects, there is still a lack of consistent and reliable measurement techniques and reliable information on reference values. In this review our understandings of the urinary profilings of boron, lithium and strontium are summarized and fundamental results obtained in our laboratory are discussed.Over the past decade we have successfully used inductively coupled plasma emission spectrometry for the determination of reference values for urinary concentrations of boron, lithium and strontium. Taking into account the short biological half-life of these elements and the fact that their major excretion route is via the kidney, urine was considered to be a suitable material for monitoring of exposure to these elements. We confirmed that urinary concentrations of boron, lithium and strontium follow a lognormal distribution. The geometric mean reference values and 95% confidence intervals were 798 μg/l (398-1599 μg/l) for boron, 23.5 μg/l (11.0-50.5 μg/l) for lithium and 143.9 μg/l (40.9-505.8 μg/l) for strontium. There were no discrepancies between our values and those previously reported. Our reference values and confidential intervals can be used as guidelines for the health screening of Japanese individuals to evaluate environmental or occupational exposure to these elements.
