It could be!Here are my results. No fires but higher Lead level than the two of you. City living = lead paint in soils?
Lead: The average level of lead found in your eggs was 0.61 micrograms per 57 gram egg. Based on this, the average adult would not be at risk for exceeding the Food and Drug Administration (FDA)'s maximum daily intake (called the Interim Reference Level) of lead for adults (12.5 micrograms per day). A child would have to eat approximately 5 eggs on a daily basis to exceed the Interim Reference Level for children (3 micrograms per day). Please note that these threshold levels are set nearly ten-times less than the actual amount of intake of lead from food required to reach the Center for Disease Control's blood reference level for lead.
Cadmium:The average level of cadmium found in your eggs was 0.15 micrograms per 57 gram egg. Based on this value, you are at no significant risk of exceeding the California Office of Environmental Health Hazard Assessment (OEHHA) threshold of cadmium associated with reproductive harm (4.1 micrograms per day) or the OEHHA Oral Reference Dose Level for cadmium consumption in food (1 microgram per kilogram of body weight).
Nickel: The levels of nickel detected in all eggs submitted to our study were significantly below the California Office of Environmental Health Hazard Assessment (OEHHA) daily threshold for nickel consumption associated with cancer risk (5 micrograms of nickel per pound of body weight).
Copper: The average level of copper found in your eggs was 24.3 micrograms per 57 gram egg. The Agency for Toxic Substances and Disease Registry’s safe consumption threshold is 4.54 micrograms per pound of body weight per day. For a 155lb person, they would not be at any significant risk of exceeding this threshold. If you would like to calculate the approximate number of eggs you would have to eat on a daily basis in order to exceed this threshold, you would multiply your body weight in pounds by 4.54, then divide by the level of copper found in your eggs. To give an example calculation, if someone weighed 155lbs and the average level of copper found in their eggs was 30 micrograms, they would perform the following calculation: (155×4.54)÷30=23.5 Therefore, the person in this example would have to eat approximately 23 eggs daily in order to exceed the threshold.
Mercury: The average level of mercury found in your eggs was 0.17 micrograms per 57 gram egg. California’s Prop 65 threshold for mercury consumption associated with cancer risks is 0.07 micrograms per pound of body weight per day. For a 155lb person, they would not be at any significant risk of exceeding this threshold. If you would like to calculate the approximate number of eggs you would have to eat on a daily basis to exceed this threshold, you would multiply your body weight in pounds by 0.07, then divide by the level of mercury found in your eggs. For example, if someone weighed 155lbs and the average level of mercury found in their eggs was 0.6 micrograms, they would perform the following calculation: (155×0.07) ÷0.6=18.1 Therefore, the person in this example would have to eat approximately 18 eggs daily in order to exceed that threshold.
Arsenic: The average level of arsenic found in the eggs you submitted to our lab was below the detection limit and thus is not currently a concern.
There was a thread a while back with sick chickens. It turned out to be lead poisoning from an old shed that had, I think, paint chips blown off from the wind. Even though lead paint has been banned since the 70s, Lead is still a very common heavy metal poison.
