Where would i stand with my little boy?

This is very difficult to explain but here goes...over the past year my partner, myself and our children have gone through hell and back with all the essments and appointments for our son and are finally coming towards a diagnosis.Medical proffessionals have told me my sons on the autistic spectrum but are not quite sure yet as to which type of autism it is. Now there is another problem...my partner works within an industry that is contaminated with lead and we have recently disscovered that his lead levels are a hugh 52 which is above action level. only through finding this out have i gone onto the internet and found plenty of info about illnesses and problems this can bring into the home and to my horror over half of them my son has suffered with. He is now going to under go blood tests again for lead poisioning so there is now another factor. I feel really sad about this and so annoyed that we have never been made aware of the companys health and safety where lead is concered. We never knew how serious this was until i looked on the laptop and i feel like our son may have suffered at the hands of my partners boss. Also because it could of effected him as a baby and was in his system as his brain was developing then nothing can be done only bring the levels down if they are high. Another symptom is low iron and we was actually told 3 months ago off our sons doctor that he has no iron stores and he is on medication for that. we are coming closer to his diagnosis but now this fact is there to look at in great detail and as it stands i cant imagine it being true. My partner does not even get protective clothing and has only just been told he has to wash his clothes at work. Are we supposed to just know all this without a boss telling us. I am pregnant with our 3rd child and i have just found out that lead goes into a mans sperm and can cause misscarriages and stillbirths. I am very confused right now. If our son has suffered because of this i will be taking this firm through court- its so wrong- but would i stand a chance?? Sorry this is so long but i had to let this all out for you to get a better picture of our situation. Thankyou very much for reading.
