Milk produced by contaminated cattle can be diluted to a lower lead concentration and sold for consumption.In Bangladesh, lead compounds have been added to turmeric to make it more yellow. This is believed to have started in the 1980s and continues as of 2019. It is believed to be one of the main sources of high lead levels in the country. In Hong Kong the maximum allowed lead parts per million is 6 in solid foods and 1 in liquid foods. Paint
Some lead compounds are colorful and are used widely in paints, and lead paint is a major route of lead exposure in children. A study conducted in 1998–2000 found that 38 million housing units in the US had lead-based paint, down from a 1990 estimate of 64 million. Deteriorating lead paint can produce dangerous lead levels in household dust and soil. Deteriorating lead paint and lead-containing household dust are the main causes of chronic lead poisoning. The lead breaks down into the dust and since children are more prone to crawling on the floor, it is easily ingested. Many young children display pica, eating things that are not food. Even a small amount of a lead-containing product such as a paint chip or a sip of glaze can contain tens or hundreds of milligrams of lead. Eating chips of lead paint presents a particular hazard to children, generally producing more severe poisoning than occurs from dust. Because removing lead paint from dwellings, e.g.
Hypervigilance can be thought of as a way to appraise threatening social information, but in contrast to adaptive vigilance, hypervigilance will produce elevated levels of arousal, fear, anxiety, and threat perception. Rumination is another possible response to threatening social information. Rumination can be related to the paranoid social cognition because it can increase negative thinking about negative events, and evoke a pessimistic explanatory style. Judgmental and cognitive biases
Three main judgmental consequences have been identified:
The sinister attribution error: This bias captures the tendency that social perceivers have to overattribute lack of trustworthiness to others. The overly personalistic construal of social interaction: Refers to the inclination that paranoid perceiver has to interpret others’  action in a disproportional self-referential way, increasing the belief that they are the target of others’ thoughts and actions. A special kind of bias in the biased punctuation of social interaction, which entail an overperception of causal linking among independent events. The exaggerated perception of conspiracy: Refers to the disposition that the paranoid perceiver has to overattribute social coherence and coordination to others’ actions.Meta-analyses have confirmed that individuals with paranoia tend to jump to conclusions and are incorrigible in their judgements, even for delusion-neutral scenarios. Research
A study suggests that combining cognitive behavioral therapy (CBT) with SlowMo, an app that helps notice their "unhelpful fast-thinking" might be more effective for treating paranoia in people with psychosis than CBT alone. See also
