Lead exposure alters the development of agonistic behavior in golden hamsters.
TLDR
The data support the association between exposure to low doses of lead and aggressive behavior in boys and show a dose-specific effect of lead exposure on the development of aggression during puberty at doses resulting in blood levels well below 20 microg/dl.
Stress and the development of agonistic behavior in golden hamsters
Changes in Behavior and Learning Ability of Rats Intoxicated with Lead
TLDR
The obtained results revealed a dose dependent increase in the feeding time, drinking frequency, licking frequency, scratchingfrequency, licking litters, nest building and retrieving frequencies, while standing time increased significantly in rats treated with 1.5g/l lead acetate than other treated groups and control, on contrary lying time decreased gradually in a doses dependent manner.
Lead exposure potentiates predatory attack behavior in the cat.
Experimental design affects social behavior outcomes in adult zebrafish developmentally exposed to lead.
TLDR
Since the presence of refuges that is, environmental enrichment, reduced Pb(2+)-induced agonistic behavior in both sexes, experimental spatial design can be considered an important factor when interpreting behavioral outcomes.
Sub-lethal exposure to lead is associated with heightened aggression in an urban songbird.
Effects of arsenic exposure during early postnatal period on Leydig cells of rat testis
TLDR
The observations of the present study are indicative of adverse effects on rat testes Leydig cells following exposure to low doses of sodium arsenite during critical window periods and are suggestive of irreversible damage to testicular tissue.

Developmental changes in pre-adult behavior in confined colonies of golden hamsters.
TLDR
Eight litters of hamsters living in a large enclosure were observed from birth to 120 days, where females are normally dominant, and a gradual shift followed in the relative aggressiveness of the sexes.
Behavioral manifestations of prolonged lead exposure initiated at different stages of the life cycle: II. Delayed spatial alternation.
TLDR
The results of this study suggest that both early and late stages of the life cycle must be considered periods of enhanced vulnerability to Pb-induced behavioral changes.
Behavioral and Neurobiological Consequences of Social Subjugation during Puberty in Golden Hamsters
TLDR
The results establish puberty as a developmental period sensitive to environmental stressors and show that changes in the vasopressin and serotonin systems can correlate with behavioral alterations, supporting the role of these two neurotransmitters in the regulation of aggression.
Effects of neonatal lead exposure on apomorphine-induced aggression and stereotypy in the rat.
TLDR
These results provide a further demonstration of persistent behavioral abnormalities resulting from early exposure to lead at levels which do not affect weight gain or mortality.
