Tin-Lead Solder Health Hazards: Effects, Lead-Free Solder, & Safety Measures with 3M ABEK2P3 Mask

Lead is carcinogenic and the risk of soldering is quite high.
However, lead tin is better. It has better mechanical strength. Therefore, new electronic ones break down quickly. because factory regulations require lead-free soldering.

you scared me with this topic :D

I wonder if it is possible to somehow calculate how many, for example, a gram per day is a safe range, as long as we can talk about a safe range.

Even if it was possible, how would you like to check how much you absorb it?

It is definitely forbidden to use it in workplaces.

The EU directive specifies the scope of equipment in which the PB-Sn eutectic alloy can be used. From what I remember, until the end of 2017. the PbFree standard will cover medical equipment, and there are also attempts at military equipment. In consumer equipment, it already applies to all products.
The change of alloy goes hand in hand with the technology of the housings and the methods of soldering them. Here we come to another problem, i.e. the change of technological habits related to the PbSn alloy so far. There are also some changes in the technology of covering the plates with solder mask and the geometry of the contact fields for individual housings. It's a lot of changes, but there is no advice.

The toxicity level of the PbSn alloy cannot be equated with the level of lead toxicity. The proportion of the alloy is so selected that it is possible to mix the crystals of one element with another. This means there are no pure lead precipitates. This in turn reduces the possibility of poisoning with this element. Fluxes and activators are more poisonous than the alloy itself. Considering the soldering temperature slightly increased by 15%, which is quite a lot. It is not by accident that if the smoke is acrid, the body thus points out that the environment is not the healthiest. It is worth considering the quality of the fluxes used.

Even the simplest portable extractor with a carbon filter will solve the frosting of the studio. Although when soldering in a small furnace, it is worth taking care of a solid permanent exhaust connected to the furnace.

You can't outsmart a directive this way. You're scheming in the wrong direction. Changes in the housing technology and the current load of the housing-PCB connectors will force you to use a lead-free alloy sooner or later. Compare both the thermal and electrical resistance of the PbSn and Sn alloys. In BGA housings, there is also an aim to reduce the amount of alloy, i.e. the size of the balls, and this is an irrevocable trend.
Do you have doubts? See what the motherboard of the lapopa looks like today and what it looked like 7 years ago, which is more or less when PBFree began to be introduced on a mass scale.

But you know ... gutters are usually soldered outside in the open air, in a ventilated place, and ie in a hall where ventilation is not effective.

All the talk about the harmfulness of lead is the same fucking thing that whoever had been doing five years in the states with asbestos when he came back the moment ended with cancer.

Actually yes. And let's end there The roof of the old garage was covered with asbestos, and by the fence there were 2 pallets of that material, and I am still alive.
In order for lead to actually kill a man, it would have to eat him

You can also do such a test and everything will be clear.

Probably within a certain limit

The lead chelating agent from the body is sodium citrate contained in tin-flavored drinks. Although insiders, on the basis of long-term tests, argue that lead is best rinsed with booze and in second place with beer . It is also forbidden to drink tap water because, first of all, only animals drink water and secondly, it is unhealthy because some of the installations are made with lead. Why poison yourself when you can drink what is healthy?
